ENTRY LEVEL DISC-BRAKE TRIATHLON BIKE

not your average entry level bike

It's difficult to label the PRfour Disc an "entry level" bike. With superbike frame shaping and proven disc brake technology featured on our flagship PRsix Disc model, the PRfour is more than just your average "entry level" triathlon bike. QR SHIFT+ Aerodynamics minimizes drag and maximizes overall efficiency while thru-axle disc brakes increase power transfer through increased lateral frame stiffness. Just as aero, stable, comfortable, and fit friendly as our PRfive Disc – the PRfour Disc is more affordable due to a more compliant modulus carbon-fiber layup.
